Strang Youtube stutter
by alp_c from LinuxQuestions.org on (#5QJRR)
Dear all,
I am experiencing a very strange way of stutter when watching Youtube videos. Every couple of minutes it repeats the previous ~0.5 sec of audio and video. There is no regular pattern of when it occurs. All other applications run without any problems.
The system is a Core2Duo desktop with 4GB RAM, 160GB SSD. I'll paste the HW specs at the end of this post. It is set up as a triple boot configuration:
1) Linux Mint 20.2 Cinnamon with proprietary Nvidia-340-legacy drivers, X11, latest Firefox, kernel 5.4, SystemD init.
2) Devuan 4 Gnome (Debian Bullseye based) with Nouveau drivers, Wayland, latest Firefox-ESR, kernel 5.10, Runit init.
(2a) previously I also tried Devuan 4 Mate with Nouveau drivers, X11, latest Firefox-ESR, kernel 5.10, OpenRC init)
3) MS Windows 8.1 with latest Firefox
All GNU/Linux systems are having the issue, on Windows however it does NOT occur.
It appears to be independent of distro, kernel version, GPU drivers, X11/Wayland, Firefox version, desktop environment and init system. No peaks in resource usage (RAM/CPU/SSD). No entries in dmesg. I am using Ethernet rather than Wifi, if that matters. Memtest shows no errors. SMART values of SSD are okay.
Could anyone think of what could be causing this? I've searched the web but could not find any solution so far.
Greetings
